To find the 7-digit number using the given clues, let's analyze each clue one by one:

1. "It is a 7-digit number." This clue tells us that the number has seven digits.

2. "It has a 0." This clue tells us that one of the digits in the number is 0.

3. "The greatest digit is in the hundred thousands place." This clue tells us that the largest digit appears in the hundreds thousands place. Since the number is only 7 digits long, the greatest digit can be between 1 and 9.

4. "The value of the digit 1 is 1,000,000." This clue tells us that one of the digits in the number represents 1,000,000. Since the digit 1 is already used, we can exclude it from being in the hundreds thousands place. So, the greatest digit is not 1.

5. "The digit 6 stands for 6,000." This clue tells us that one of the digits in the number represents 6,000.

6. "The value of the digit 5 is 5 ones." This clue tells us that one of the digits in the number represents a value of 5 ones, which is just 5.

7. "The digit 8 has a value greater than 700 but less than 1,000." This clue tells us that one of the digits in the number represents a value greater than 700 but less than 1,000. Since the digit 0 is already used, the remaining digits are 2, 3, 4, 5, 6, 7, and 9. We can exclude 2, 3, 4, 5, and 9 as they are not greater than 700. So, the digit 8 is the one that satisfies this clue.

8. "The value of the digit 7 is 7 ten thousands." This clue tells us that one of the digits in the number represents a value of 7 ten thousands, which is 70,000. The remaining digits are 2, 3, 4, and 9.

Based on the clues, we can deduce that the number is in the format of _ _ _ _ _ _ _. Now, let's combine the information we have:

Since the greatest digit is in the hundreds thousands place, the hundreds thousands digit can only be 6 or 7. However, the value of the digit 7 is given as 70,000, so the greatest digit must be 7.

Next, we know that the value of the digit 6 is given as 6,000, so the ten thousands digit must be 6.

We also know that the digit 8 has a value between 700 and 1,000, so it must be the thousands digit.

Now, let's fill in the remaining digits. Based on the available digits (0, 1, 2, 3, 4, and 9), we can assign values to the hundreds, tens, and ones places.

One possible arrangement that satisfies all the clues is:
7 _ 8 6 0 5 0.

Therefore, the 7-digit number based on the given clues is 78,605,0.
